Model-independent reconstruction of the cosmological scale factor as a function of lookback time
Jian-Chen Zhang, Jing Zheng, Tong-Jie Zhang
We present a model-independent method of reconstructing scale factor against lookback time from the Observational Hubble parameter Data (OHD). The reconstruction method is independ…

A Model-Independent Measurement of the Spatial Curvature using Cosmic Chronometers and the HII Hubble Diagram
Jing Zheng, Fulvio Melia, Tong-Jie Zhang
We propose a model-independent way to determine the cosmic curvature using the Hubble parameter measured with cosmic chronometers and the comoving distance inferred f…
